Epson 200 - Manual (Page 31)

In the Table 2-1, if the control sequence is executed in incremental order, the carriage motor rotates
clockwise (CW). (The CR moves from 1st column to 80th column.)
Signals output from ports P105, P106, and P107 of the CPU determine the reference trip current level
used by the motor driver IC for drive current control. Table 2-2 lists the connection of the output
signals and the reference trip current levels.
